“Since losing our home in the May 19, 2013 tornado in Oklahoma, we decided to buy an RV to live in before instead of rushing right into major decisions. It’s a big adjustment and not knowing a lot about various products; I’ve tried many. Some worked short term. Some seemed fine until summer came along and oh boy, that really tests these products! This is the only one I found that we have absolutely no odor problems with and as long as I put two in when we first empty the tank, then one every 4-5 days, we can go (with two of us), almost three weeks before having to empty the tank and have no odor. These things are great and I’d recommend them to anyone who can’t stay hooked up to sewage to keep your bathroom odor free. I’m totally sold! Great product!”



“After each black tank dump, I just put a gallon or two of clean water back into the tank and drop one of these packets in and voila!, no odors until the next time the tank needs dumping. I’ve never experienced any odors in our RV while using this product.”


“Wow. This stuff works great. I have a small camper and I have a 5-gallon bucket with a toilet seat (also purchased on Amazon) that I use for a potty. I put kitty litter (in a trash bag, of course) and one of these deodorizer packets in the bucket and that sits inside a small privacy tent which is my camping “outhouse”. These deodorizer packets kept things fresh smelling the entire time. If these worked under those conditions then they’ll work anywhere. I definitely recommend this product.”



“These work, and they work well. Plain and simple. My wife and I just moved into a 5th wheel full time. Stepping on that toilet pedal and opening that hole above the black water tank is no longer a concern. It was terrifying before we got these. They do an amazing job at eliminating the odor. As far as breaking waste and paper down, it seems like it’s doing the job as well.

These work like magic, and that’s worth 5-stars to me.”
